WASTE HEAT RECOVERY SYSTEM

Provided is a thermal energy recovery device enabling recovery of thermal energy of exhaust gas exhausted from an internal combustion engine, and smooth exhaustion of the exhaust gas to an outside. The thermal energy recovery device (1) includes an economizer (11) connected to an exhaust gas pathway (100) through which the exhaust gas exhausted from the internal combustion engine flows and a heatmedium pathway (12) through which a heat medium flows, and heating the heat medium through heat exchange between the exhaust gas flowing into from the exhaust gas pathway(100) and the heat medium flowing into from the heat medium pathway (12), a thermal energy recovery unit (10) connected to the heat medium pathway (12), and recovering thermal energy of the heat medium heated by the economizer (11), and a blowing machine mechanism (30) arranged in the exhaust gas pathway (100), and pressurizing the exhaust gas flowing through the exhaust gas pathway (100). 本发明提供种能够将从内燃机排出的排气的热能回收、并将该排气顺畅地向外部排出的热能回收装置。热能回收装置（1）具备：节热器（1
